CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 347,001, dated August10, 1886.

Application filed May 28, 1886.

To all whom it may concern.-

Be it known that I, MICHAEL MAHER, a citizen of the United States,residing at Fremont, in the county of Dodge and State of Nebraska, haveinvented a new and useful Improvement in Oar-Couplings of which thefollowing is a specification.

My invention relates to an improvement in car-couplings; and it consistsin the peculiar construction and combination of devices that will bemore fully set forth hereinafter, and particularly pointed out inthe'claim.

In the drawings, Figure 1 is a vertical longitudinal sectional View ofmy invention,with the detent and the coupling-pin in position to receivethe coupling-link when the cars come together. Fig. 2 is a similar viewshowing the coupling-link attached to the draw-head when the cars arecoupled. Fig. 3 is a front elevation.

A represents the draw-head, which is provided with the usual flaredmouth,B. To the outer end of the draw-head, and intersecting the centerof the mouth or opening, is a vertical opening, 0, in which is securedthe coupling-pin D. In the upper side of the drawhead, in rear of theopening 0, is made a longitudinal vertical slotted opening E.

F represents a detent, comprising a lever which is fulcrumed in theopening E, and has a rearwardly' and upwardly extending arm, f, that isweighted at its outer end, and avertical downwardly-extending head, f,the front side of which is curved. The rear end of the arm f extendsthrough the slot E and above and rearwardly from the draw-head, and thehead f is located in rear of the mouth of the draw-head and normallydirectly in line with the opening 0.

Serial No. 903.556. (No model.)

G represents the usual coupling-link.

The operation of my invention is as follows: In order to couple the carstogether,the coupling-pin G is first withdrawn vertically from the lowerend of the opening 0 until the lower end of the said coupling-pin restsupon the upper end of the head f. The said head then depends across thecenter of the opening in rear of the mouth of the draw-head. When thecars come together, the coupling-link en ters the Ldraw-head and strikesagainst the detent-head f, thereby raising the weighted arm f, andcausing the upper end of the said detent-head to release thecoupling-pin, when the latter drops vertically by its own gravity andsecures the link to the draw-head,as shown in Fig. 2.

A. car-coupling thus constructed is cheap and simple, is strong anddurable, is not likely to get out of order, and performs the operationof coupling the cars automatically.

Having thus described my invention, I claim- The combination of thedraw-head having the Vertical opening 0 and the longitudinal verticalslotted opening E with the detent F, fulcrumed in the opening E, andhaving the rearward] y and upwardly extending weighted arm j, and thedepending detent-headf, and

the coupling in the opening 0, for the purpose set forth, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
